UNSPSC 46191624: Nitrogen cylinder

Nitrogen gas cylinders are used to cover, purge or stir chemicals or molten metals. The gas is used to extinguish fires and for freezing of soil. It can also be used to pressurize devices or pneumatically convey chemicals, while keeping out contaminates like oxygen or water.

UNSPSC 46191624 Nitrogen cylinder is a Commodity code that does not align with the work actually being solicited under it in recent state and local procurement. The opportunities posted against this code span fire protection system services—fire extinguisher inspection, maintenance, hydrostatic testing, recharging, and replacement; fire alarm system testing and certification; fire sprinkler system inspection and maintenance; and related suppression-system work. None of these solicitations describe procurement of nitrogen cylinders as a discrete product line or component. The code appears to have been applied by posting jurisdictions as a catch-all or general classification despite the substantive mismatch between the code's nominal scope (a specific industrial gas product) and the service-oriented nature of the work being bought.

The issuing bodies include counties (Brevard, Escambia, Pinellas, Maricopa, Waukesha, Orange, Boulder, Bibb, Harlingen ISD, Douglas), cities (Bradenton, Milpitas, Dallas, Palo Alto, Tallahassee, Columbus), school districts (Cherokee County in Georgia, Hillsborough County in Florida, Bibb County in Georgia), transit authorities (Orange County Transportation Authority), special-purpose districts (Maricopa County Community College, Events DC), and state agencies (Texas Department of Public Safety, Texas Military Department). Geographic activity spans Florida (Brevard, Escambia, Hillsborough, Pinellas, Brevard ISD), California (Milpitas, Palo Alto), Texas (Dallas, Harlingen, Fort Bliss, Irving), Georgia (Cherokee County, Douglas County, Bibb County), Colorado (Boulder County), Wisconsin (Waukesha), Arizona (Maricopa), and Washington DC. Representative recent opportunities include Brevard County's sole-source procurement for UPF brand polypropylene water and foam tank assemblies for Fire Rescue apparatus (November 2025, $11,000); Bradenton's IFB for comprehensive fire systems testing, inspections, and repair across nine city locations (October 2026, due October 21); Pinellas County's ITQ for fire extinguisher and kitchen hood inspection services across 159 locations for an estimated $262,000 over five years (May 2026, due May 21); and Milpitas's IFB for fire extinguisher inspection and maintenance services at 17 city locations over five years (October 2026, due November 10). The code shows substantial recent activity, but pursue this category only if your firm can reposition its service line or if you believe the posting jurisdiction has mislabeled the opportunity—the code itself is not a reliable intake gate for this market.
